Farmers wanted a rebate on bait similar to during the locust plague and a pesticide mixing site in the Mallee so farmers could use their own grain for bait.

The VFF's Andrew Weidemann says farmers are now being told they face a 40-day wait to access commercial bait.

"That's probably the bigger issue than the cost at the moment, not having enough supply at a critical time when people are actually trying to plant their crop or just trying to control the mice with the crop coming up," he said.

"There is certainly a reasonable amount of distress out there and that's quite evident when you talk to growers."

However, Mr Walsh says the Government is working with industry to ensure there is an adequate supply of bait.

"As I see it with the mice control program, [it] is making sure there is some other suppliers in the market, to ... get enough product out there, so people don't have to wait as long as they're having to wait at the moment and a bit of competition will help reduce the price," he said.

"The DPI [Department of Primary Industries] has been working with the industry to get an emergency use permit so other players can go into the market."
